Devi Morris has lots of problems - and not the fun, easy-to-shoot kind either.

After a mysterious attack left her short of several memories and one partner, she's determined to keep her head down, do her job and get on with her life. But even though Devi's not looking for it this time, trouble keeps finding her.

She sees ghostly creatures no one else can, the inexplicable black stain on her hands keeps getting bigger and she can't seem to stop getting into compromising situations with a man she's supposed to hate. But when a deadly crisis exposes far more of the truth than she bargained for, Devi discovers there are worse fates than being shot - and that sometimes the only people you can trust are the ones who want you dead.
